High-lift linkage
The new high-lift loader linkage option is designed specifically for applications that can benefit from increased lift height and increased reach of the loader linkage. The newly designed loader arm assembly can provide up to 10 percent more lift height and reach compared with the standard loader linkage equipped with a similar work tool interface whether pin-on, IT (Integrated Tool Carrier) coupler or ISO coupler. A 918M configured with both a high lift linkage and 20.5 tires will have a bucket pin height over 13 feet, 5 inches (4.1 meters).

Fusion coupler
With the addition of the Caterpillar designed Fusion Coupler System to the 918M’s option list, buyers now have the choice of three couplers. Designed for optimum performance and long-term durability, the Fusion coupler uses an advanced constant pressure wedging mechanism to create a tight, rattle-free fit with work tools.
The patented locking system eliminates the play and thus eliminates the associated wear. The Fusion coupler is designed to apply constant hydraulic pressure to wedges that continually pull the work tool tight to the coupler in two directions — in and down, providing secure tool control and increased productivity. The coupler is available for Fusion-compatible work tool attachments.

Tire choices
Three new 20.5R25 tires for the 918M offer a number of benefits compared to the standard 17.5R25 tires, including up to 20 percent more tire life and increases in traction, stability and tipping capacity — all resulting in reduced operating costs.
Available for the North American market, the three new tire options include the general-application Goodyear E/L-2A “Sure Grip Loader,” a 12-ply-rated bias tire with directional and self-cleaning tread; the Michelin “Xsnoplus,” specially designed for operation on snow and ice, and incorporating a non-directional tread pattern with excellent self-cleaning characteristics; and the Michelin XHA2 radial, a wide-lug tire with non-directional tread, heavy shoulders and protected sidewalls for heavy-duty applications.

Width-over-tires is approximately 91 inches for the larger 20.5R25 tires. All three tire options must be used with the Fusion coupler or with the optional high-lift loader linkage to ensure that work tools rest level on the ground. An oscillation limiter eliminates tire-to-fender interference.

Guarding
The new guarding options, which can be used with currently available steel-front fender deflectors, provide protection for vulnerable areas:
• Headlight guards surround the front light assemblies and protect from debris falling from the bucket
• Hitch guards protect the 918M’s articulation point by providing barriers on both sides of the hitch to prevent material from collecting in the frames, while allowing ready access to service points
• Powertrain guard mounts beneath the transmission and related components; provides an access panel to facilitate oil changes
• Drive shaft guard mounts beneath the front driveshaft for protection from debris and obstacles
• Crankcase guard mounts beneath the engine to protect the oil pan
